     Said catalyst is several times (5 to 100) more active than prior art catalysts and provides for a high yield of the product, which may be as high as 1000 kg/g of a transition metal.

This invention relates to catalytic polymerization processes, and more particularly it relates to complex catalysts for polymerization, copolymerization, and oligomerization of olefins and diolefins. Said catalysts are widely used in the manufacture of polyethylene, polypropylene, and copolymers of ethylene with propylene and with butene, and also for producing ethylene-propylene-diolefin rubbers and oligomeric olefins according to the so-called low-pressure method (Ziegler process).

Known in the art are catalysts for polymerization, copolymerization, and oligomerization of olefins, which are binary systems consisting of components of a compound of a transition metal having the formula MX_(n), where M is a metal or oxide of a metal belonging to IVA-VIA or VIII groups of the Periodic System, X is a halogen, hydrogen, alkoxy-, aryloxy-, amido-, or cyclopentadienyl group, and n is an integer denoting the valency of the metal M, and of a component of an organometallic compound having the general formula M'R_(p) Z_(k-p), where M' is a metal of I-III groups of the Periodic System, R is a hydrocarbon radical, Z is a halogen, alkoxy-, or amido- groups, k is an integer denoting the valency of the metal M', and 1≦ p≦ k (see, for example, Norman G. Gaylord, Hermal F. Mark. Linear and stereoregular addition polymers: polymerization with controlled propagation. 1959. Interscience Publishers, Inc., New York).

In order to increase the activity of said complex catalysts for polymerization and copolymerization of olefins, and also in order to control the kinetic parameters of the polymerization process induced by them, and the properties of the polymers formed, separate components of the catalyst, or the products of their interaction are fixed on a carrier of an inorganic type, this carrier being oxides, hydroxides, or oxyhalogenides of certain metals.

Indeed, the activity of such catalysts increases, but the inorganic carrier remains in the obtained polymer and this increases its ash content. In recent years attempts were made to eliminate this disadvantage. To this end, catalysts were offered, these being catalysts for polymerization, and copolymerization of olefins and diolefins on polymer carriers; carbon and hetero-chain polymers, containing fragments capable of fixing said compounds, MX_(n) or M'R_(p) Z_(k-p). For example a catalyst is known, which is a product of interaction of the TiCl₄ and hydroxyl groups of crushed cellulose, polyatomic alcohols, polyglycols, activated with diethyl-aluminium chloride (British Pat. No. 834,217, CII(1)BOIj, May 4, 1960). Known also is a catalyst for polymerization and copolymerization of olefins, consisting of a product of interaction of TiCl₄ with hydrolyzed copolymer of ethylene and vinylacetate, or with vinyl chloride, containing from 1 to 20 percent of hydroxyl groups, activated with an organoaluminium compound. TiCl₄ is fixed on such polymers due to their hydroxyl groups when the component solutions are mixed together, the chemistry being as follows: ##STR3## (French Pat. Nos. 1,405,372 and 1,588,369).

Known also are catalysts for polymerization and copolymerization of olefins containing the product of reaction of MX_(n) with nitrogen-containing polymers, having in their compositions the functional amino-, imino-, imido-, urethane-, nitrile, or nitro-group (Belgian Pat. No. 706,659, Class CO8f, May 17, 1968), and also with sulphur-containing polymers, for example, polysulphone (Belgian Pat. No. 690,008 Cl.C08f, May 22, 1968), activated with organoaluminium compounds. Moreover, such catalysts are the products of interaction of MX_(n) with carbon-chain polymers having fragments containing elements with unshared pairs of electrons (>N--, --O--, --S--, or >P-- Inventor's Certificate of the USSR, No. 420,330, Cl.BOIj, 11/84, 1974), activated with organoaluminium compounds.

Finally, catalysts of polymerization and copolymerization are known consisting of a mixture of MX_(n) and organoaluminium compound fixed on a polymer carrier, containing groups >C═ O, >C.tbd. N-, or C═ N (Belgian Pat. No. 716,375, cl. CO8f, Dec. 11, 1968).

However, the above-named catalysts for polymerization and copolymerization do not meet the requirements of modern industry producing polyolefins, insofar as they have a number of disadvantages that considerably limit, and in some cases exclude the possibility of using them. Most essential disadvantages inherent in the known catalysts of polymerization and copolymerization of olefins are listed below.

1. Relatively low activity in reactions of polymerization and copolymerization of olefins and diolefins (for example, the yield of polyethylene does not exceed 1-2 kg/g M), due to the fact that a significant part of the component (MX_(n) or M'R_(p) Z_(k-p)) fixed on a polymer carrier is confined in the volume of the polymer carrier and does not take part in the formation of active centres of polymerization. The degree of utilization of the applied components is not greater than 2- 3 percent.

2. The necessity of a complex operation for washing off the residues of the catalyst (after its use in the polymerization process) which decrease the stability of the obtained products.

3. The consumption coefficients, with respect to the second component of the catalyst (M'R_(p) Z_(k-p)), are high when MX_(n) is fixed on the polymer carrier. This involves an unreasonable consumption of the catalyst in the reaction with vacant fragments that are always present in such polymer carriers.

4. The polymer carrier of the catalyst produces an unfavourable effect on the properties of the obtained polyolefins or their copolymers since it is not always sufficiently compatible with the obtained products owing to the different nature thereof.

5. The above-named polymer carriers obtained by the polymerization or copolymerization with expensive monomers are not easily available.

6. The properties of the obtained products of polymerization (molecular weight, bulk weight, and composition) are difficult to control.

It is an object of this invention is to provide a catalyst for polymerization and copolymerization of olefins and diolefins that would ensure higher yields of polymer compared with the known catalysts.

Another object of the invention is to provide a catalyst for polymerization and copolymerization of olefins and diolefins that would provide conditions for easy control of the bulk and molecular weight of the products formed in the polymerization process.

Still another object of the invention is to provide a catalyst for polymerization and copolymerization of olefins and diolefins that would eliminate the necessity of washing off the residual catalyst from the obtained polymers and thus simplify the process flowsheet.

Moreover, the object of this invention is to provide a catalyst for polymerization and copolymerization of olefins and diolefins having such properties that would widen the limits of its uses.

Yet another object of the invention is to provide a catalyst for polymerization and copolymerization of olefins and diolefins that would incorporate a polymer carrier which is an industrial product on the one hand, and, with respect to its properties, would be identical or close to the obtained polymers on the other hand.

Said objects have been accomplished by the provision of a catalyst for polymerization and copolymerization of olefins and diolefins, which, according to the invention, is one of the following components: component A, which is actually a compound having the formula MX_(n), where M is a metal belonging to IVA- VIA groups of the Periodic System or cobalt, X is a halogen, hydrogen, cyclopendadienyl, alkoxyl, aryloxyl, or amido group, and n is an integer denoting the valency of the metal M; component B, which is an organometallic compound having the formula M'R_(p) Z_(k-p), where M' is a metal of I- III groups of the Periodic System, R is a hydrocarbon radical, Z is a halogen, hydrogen, alkoxy-, aryloxy-, or amido group, k is an integer denoting the valency of the metal M', and 1=p= k; component C, which is a product of interaction of the above-named MX_(n) and M'R_(p) Z_(k-p) having the formula MR_(m) X_(n-m) where m is an integer and 2≦ m≦ n; each of the above-components being bonded chemically through one of the fragments having of the formula ##STR4## where R' = H, CH₃, C₂ H₅, CH= CH₂ ; C₆ H₅,

R" = h, or CH₃ ;

R"'= h, or CH₃ ;

Y= oh, nhr', sr', coch₃, ##STR5## ch₂ nhr', ch₂ sh, cooh, ococh₃, cooch₃, c.tbd. n, n(r')₂, ≦ sor' wherein R' is as defined above,

t is the mean degree of polymerization equal from 4 to 5000, only with the surface of a carbon-chain polymer carrier, the component A being activated with the compound M'R_(p) Z_(k-p), and the component B being activated with the compound MX_(n).

The interaction between the compounds MX_(n), M'R_(p) Z_(k-p) and MR_(m) X_(n-m) with carbon-chain polymers containing the above-named fragments on their surface was not known in the prior art.

The catalyst of this type can be represented as ##STR47##

A catalyst containing component C which is a product of interaction of MX_(n) and M'R_(p) Z_(k-p), having the general formula MR_(m) X_(n-m), where M, X, n, M', m, R, Z, p and k as specified above, bonded chemically through the fragment ##STR48## where t= 4- 9, with the surface of a polymer carrier.

The catalyst of this type can be represented schematically as follows: ##STR49##

Some representatives of this catalyst are:

1. Ti(CH₂ C₆ H₅)₄ bonded chemically with the surface of polyethylene-gr.-polyallyl alcohol.

2. V(CH₂ C₆ H₅)₄ bonded chemically with the surface of polyethylene-gr.-polyallyl alcohol.

XXIII. A catalyst containing component C, which is a product of interaction of said MX_(n) and M'R_(p) Z_(k-p), having the formula MR_(m) X_(m-n) bonded chemically through the fragment ##STR50## where t = 4- 9, with the surface of a polymer carrier.

The catalyst can be represented schematically as follows: ##STR51##

The proposed catalyst for polymerization, copolymerization and oligomerization of olefins and diolefins can be prepared by the reaction of a suspension of a polymer carrier in hydrocarbon or halohydrocarbon solvents with one of the compound (or its solution) having the formula MX_(n), M'R_(k) Z_(k-p), or MR_(m) X_(n-m), with susequent isolation by chemical methods of free products, and activation of the obtained component A with a compound having the formula M'R_(p) Z_(k-p), or combination of the obtained component B and MX_(n).

An example of application of MX_(n) onto the surface of polymer carriers (preparation of component A of the catalyst) is the reaction of VCl₄, and also Ti(OC₄ H₉)₄, with polyethylene-gr.-polyallyl alcohol: ##STR52##

This is the path along which the reaction for preparing component A follows, provided MX_(n) is chemically bonded with the surface of the polymer carrier through a fragment incorporating one of the following groups γ:

    --OH, --NH.sub.2, >NH, --COOH, R'NH, R'OH, or --CH.sub.2 SH.

it should be noted that in contrast to typical homogeneous catalysts on the basis of (C₅ H₅)₂ TiCl₂, Ti(OC₄ H₉)₄ or VO(OC₂ H₅)₃, activated with M'R_(p) Z_(k-p), the proposed catalyst on the basis of these two compounds of transition metals (component A), activated with M'R_(p) Z_(k-p), is a heterogeneous catalyst. If the fragment incorporates one of the functional groups Y: SR', COCH₃, CH₂ SR', OCOCH₃, COOCH₃, C .tbd. N, N(R')₂, --S, --SO₂ R', --SOR' ##STR53## component A is formed by the donor-acceptor mechanism (formation of complex compounds). The diagram below shows a case where Y is C .tbd. N: ##STR54##

Component B of the catalyst for polymerization and copolymerization of 1 olefins and diolefins is prepared by the reaction of a suspension of a polymer carrier and said fragment with M'R_(p) Z_(k-p) (or its solution is a hydrocarbon solvent), for example, according to this diagram: ##STR55##

The catalyst containing component C is obtained by the reaction of MR_(m) X_(n-m) with a polymer carrier containing said fragments, for example as follows: ##STR56##

Carriers for catalysts for polymerization and copolymerization of olefins and diolefins are prepared as follos. Carbon-chain polymer is processed mechanochemically, with radiation, or by chemical action, in the presence of compounds having the formula ##STR57## where R', R", R"' and Y are as specified above, in other words, compounds that contain double carbon-carbon bond on the one hand and a functional group capable of fixing MX_(n), M'R_(p) Z_(k-p) ; or MR_(m) X_(n-m), on the other hand.

The double carbon-carbon bond is responsible for the graft polymerization of compounds having the formula ##STR58## with formation of said fragments, while the method of initiating the polymerization is so selected that the grafting should be only done on the surface of the carrier-carbon-chain polymer, according to this diagram: ##STR59##

Most effective is graft-polymerization of compounds having the formula ##STR60## onto the surface of carbon-chain polymers initiated by ionizing irradiation (δ-radiation of Co⁶⁰ isotope, accelerated electrons, high-frequency discharge).

This method makes it possible to utilize carbon-chain polymer of any nature (including identical or close in nature to synthezised polymer) as a carrier for components A, B and C, to control effectively the density of grafted polymer chains and their mean degree of polymerization t. Moreover, this grafting to macromolecules of the superficial layer does not produce changes in the main bulk of the carbon-chain polymer, as a result of which the grafted fragments are localized only on the surface of the carrier.

The thus prepared carbon-chain polymers with grafted fragments can be used for application onto them of MX_(n), M'R_(p) Z_(k-p), or MR_(m) X_(n-m), or the grafted fragments can undergo polymer-analogous transformations for preparing functional groups of a different nature (for example, hydrolysis of acetate groups to hydroxyl, reduction of ketone groups to hydroxyl groups, and of nitrile groups to amino groups).

The polymer-analogous transformation of grafted fragments on the surface of carbon-chain polymers occur with quantitative yield, without side processes under the suspension, and in relatively mild conditions, for example, according to the following diagram: ##STR61## Compounds of the allyl type containing groups --OH, NH, --NH₂ (allyl alcohol, allylamine, diallylamine, allylmercaptan) are selected because owing to the high degradation transfer of the chain onto the monomer, they are referred to hardly polymerizing compounds. This, in turn, leads to the absence of homopolymers of the grafted compounds of the allyl type and also to the formation of only short (t =4 -9) polymer fragments.

This latter circumstance is most important, since owing to it sufficient steric accessibility for chemical binding of MX_(n), M'R_(p) Z_(k-p) or MR_(m) X_(n-m) with functional groups of Y fragments is observed.

The catalyst for polymerization and copolymerization of olefins and diolefins, according to the invention, is formed by the reaction of component A with a compound having the formula M'R_(p) Z_(k-p) (according to diagrams I through XIX). The molar ratio of M' in M'R_(p) Z_(k-p) to M in component A is 5-500, preferably 10-100. The first step in the interconversions in the systems MX_(n) -M'R_(p) Z_(k-p) is the formation of the active polymerization bond M--R. As component A reacts with M'R_(p) Z_(k-p) the active center of polymerization also incorporates the metal-carbon bond M--R. However, depending on the nature of MX_(n) and the fragments, this active bond can be localized on the surface of the polymer carrier, for example: ##STR62## or the reaction of component A with M'R_(p) Z_(k-p) may result in full or partial detachment of the transition metal from the surface of the carrier with the formation of active centers outside the polymer carrier: ##STR63## (The arrow indicates the most probable point of incorporation of the polymerizable monomer).

The catalyst for polymerization, copolymerization, and oligomerization of olefins and diolefins, in which component A is formed from Ti(OC₄ H₉)₄ or VO(OC₂ H₅)₃ on the said carrier, induces polymerization according to the diagram XXXI, while in case with the other compounds of transition metals, the polymerization occurs on both types of active centres (XXXI and XXXII).

Active centers arise similarly in a catalyst containing component B which is present in the combination with compound MX_(n). In this case the molar ratio of M' in component B and M in MX_(n) is 20-200, preferably 50-100. in the catalyst containing component C, the active bond M--R is present already in chemical bonding MR_(m) X_(n-m) through fragment ##STR64## with the surface of the polymer carrier.

The catalyst for polymerization, copolymerization, and oligomerization of olefins and diolefins, according to the present invention, has the following advantages over the known catalysts used for the same purpose.

1. The proposed catalyst is 5-100 times more active then the known catalyst (with respect to the yield of the end product). The yield of polyethylene with the proposed catalyst can be as high as 1000 kg per gram of transition metal.

2. The high activity of the catalyst facilitates the otherwise labour-consuming operation of removing its residues from the obtained polymers, and in some cases this operation is not necessary at all, which all simplifies the flowsheet of the polymerization process.

3. The simplicity of using the proposed catalysts, consisting in that the obtained polymers become readily workable at the stage of their polymerization. They have high fluidity in the molten state, high bulk weight, and good physico-mechanical properties. Moreover, if Ti(OC₄ H₉)₄ is used for preparing component A, the fluidity index for molten polyethylene, obtained at a pressure of 10 atmospheres, is 0.1- 3.0 g/10 min, without using hydrogen as an agent controlling the molecular weight. If a catalyst in which component A contains a vanadium compound (VCl₄, VO(OC₂ H₅)₃, VOCl₃) is used, it is sufficient to have 10-15 percent by volume of hydrogen in the gaseous state to obtain polyethylene having the index of melt fluidity of 10-12 g/10 min. The bulk weight of polyethylene powder obtained with the proposed catalyst can be as high as 530 g/liter.

4. The proposed catalysts, depending on the combination of the components and the conditions of the reaction, can be used to prepare low-molecular olefin oligomers having the degree of polymerization of 10-20, which can be used independently. The yield of liquid reaction products can be 500 kg per gram of transition metal.

5. The catalysts according to the invention can be effectively used to prepare olefin copolymers, and also copolymers of olefins with dienes having practically unlimited quantities of the starting monomers, and also polyolefin rubbers, for example, copolymers of ethylene with propylene and ethylene ethylidene norbornene, capable of further transformations. The fact that they can also be used in processes of oligomerization, widens even more the field of their application. The proposed catalysts can be considered all-purpose, from the aspect of the range of products that can be prepared with their use.

6. In contrast to the known catalysts on the basis of vanadium compounds, having unstable character at temperature of polymerization, i.e. at 20-40° C. (the rate of the process attains its maximum already after mixing the components of the catalyst, and then drops sharply), the proposed catalysts, whose component A incorporates one of the compounds VCl₄, VOCl₃, VO(OC₂ H₅)₃, bonded chemically through the fragment ##STR65## with the surface of a carbon-chain polymer and activated with M'R_(p) Z_(k-p), have stable character of their action in the course of the lengthy periods of time (several hours) even at elevated temperatures (80-90° C.). This markedly simplifies the equipment used in the polymerization process. No crystallization or fibrillation occur during the polymerization process.

7. The proposed catalysts contain, as carriers, polymers identical or close (with respect to their properties) to the obtained products. For this reason, the polymer carrier should not be removed from the end product, since it does not impair its properties.

8. The process for preparing the proposed catalysts is relatively simple. Polymers of any nature can be used for preparing the catalysts according to the invention. These may be polyolefins, copolymers of olefins, polydienes, polystyrene. The fragments through which MX_(n), M'R_(p) Z_(k-p) or MR_(m) X_(n-m) are bonded chemically with the surface of carbon-chain polymers, are readily available materials. The process of their grafting onto the surface of carbon-chain polymers is simple, and can be effected by any known method of graft-polymerization.

The whole list of the above-named advantages can be attained with none of the known catalysts used for polymerization, copolymerization of olefins and diolefins.

The proposed catalysts for polymerization, copolymerization, and oligomerization of olefins and diolefins can be prepared both by batch and continuous processes, and can be used in the conditions of the existing and newly build plants manufacturing polyolefins and their copolymers by the low-pressure method.

For a better understanding of the invention, the following examples of its practical embodiment are given by way of illustration.

EXAMPLE 1

An upper part of a two-chamber glass ampoule (feeding chamber and reaction chamber) provided with separate thermostats is loaded with 4.1 g of low-pressure polyethylene (mol. weight 923,000, ash content 0.06%). The feeder chamber already contains 0.05 g of CuCl₂ (to prevent homopolymerization of vinyl acetate in the feeder chamber) and the whole ampoule is evacuated to 1 × 10⁻³ mm Hg. Then 0.9221 g of pure and freshly distilled vinyl acetate is deposited and the ampoule is sealed. The radiation gas-phase grafting of vinyl acetate to polyethylene is initiated with a source of gamma radiation, radioactive isotope Co⁶⁰. The irradiation intensity 0.8 Mrad/hr is maintained constant throughout the whole experiment; the absorbed dose is 6.0 Mrad. The feed-chamber is protected from the radiation. After grafting, the obtained product -- polyethylene-gr.-polyvinylacetate (4.9 g), -- is washed with hot benzene, and dried in a vacuum drier to constant weight. The degree of grafting (weight percent of grafted vinyl acetate to the weight of the starting polyethylene) is 12.5 percent.

The radiation-chemical yield, determined as ##EQU1## where N is the Avogadro number, ΔP is the weight of grafted monomer, D is absorbed dose (rad), M is the mol. weight of the monomer, ρ density of the polymer, is 3×10² mole/100 eV.

The hydrolysis of the grafted fragments of vinylacetate is carried out as follows. A suspension consisting of 2.5 g of the obtained polyethylene-gr.-polyvinylacetate in methyl alcohol (100 ml) is heated and 0.3 g of sodium methylate in 20 ml of methyl alcohol is slowly added (in the course of two hours) with intense stirring. The hydrolyzed copolymer is washed with methyl alcohol and then several times with distilled water, and dried to constant weight. The yield is 2.2 g of a carrier for the catalyst for polymerization and copolymerization of olefins: -- polyethylene-gr.-polyvinyl alcohol, containing 4.3 percent of hydroxy groups (determined by the Verley method) located only on the surface of polyethylene.

A three-neck flask provided with a reflux condenser, and a dividing funnel, is loaded with a suspension consisting of 1.5 g of the obtained hydrolyzed polyethylene-gr.-polyvinylacetate and 70 ml of pure and freshly distilled carbon tetrachloride. Then, at a temperature of 70° C., added to the flask is excess of TiCl₄ (0.5 g in 20 ml of CCl₄). The reaction terminates in three hours (test for gaseous HCl). The product of the reaction is transferred in an inert atmosphere into a vacuum filter, washed three times with 25-30 ml portions of HCl, and dried to constant weight, to prepare 1.3 g of light yellow powder containing 64 mg of Ti/g product -- component A of the catalyst for polymerization, copolymerization and oligomerization of olefins and diolefins.

The process of polymerization, copolymerization and oligomerization of olefins and diolefins is carried out in a thermally controlled reactor, manufactured out of stainless steel with intense stirring of the reaction mixture (≈1500 r.p.m.) with the aid of a shielded motor, and a paddle stirrer. The reactor is dried at a temperature of 60° C. in vacuum and blown with ethylene. The reactor is loaded as follows. First 0.05 g of the obtained product is loaded into the reactor having the capacity of 1.0 liter, in an inert atmosphere. The reactor is then evacuated to 1×10⁻² mm Hg, and loaded into it are 200 ml of pure and freshly distilled n-heptane. A temperature of 70° C. is maintained in the reactor with the aid of a thermostat. Ethylene is added from a special measuring cylinder in the quantity required to ensure the desired pressure inside the reactor (10 atm), and finally the co-catalyst (activator) (C₂ H₅)₂ AlCl (0.96 g) is introduced from a syringe (batcher).

The polymerization process is continued for three hours at constant pressure which is attained by continuous delivery of ethylene into the reactor as it is consumed in the polymerization process. The reaction is stopped by adding 20 ml of ethyl alcohol after which the pressure inside the reactor is dropped to 1 atm, the reaction product is unloaded, the solvent is removed from it, the product is dried to constant weight, and weighed. The yield of high-molecular crystalline polyethylene is 39 g (12 kg/g Ti).

EXAMPLE 2

Under conditions similar to those described in Example 1, the reactor is loaded with 0.06 g of TiCl₄ bonded chemically with the surface of hydrolyzed polyethylene-gr.-polyvinylacetate and 0.64 g of Al(C₂ H₅)₃. The polymerization is continued for four hours to give 15.5 g of high-molecular crystalline polyethylene (4 kg/g Ti).

EXAMPLE 3

Under conditions similar to those described in Example 1, vinylacetate (0.4 g) is grafted to polypropylene powder (4.2 g). The yield is 4.5 g of polymer carrier for the catalyst of polymerization. It is hydrolyzed in the same conditions as described in Example 1, except that o-xylene is used as the solvent and the temperature is maintained at 85°-90° C.

1.4 g of the obtained hydrolyzed polypropylene-gr.-polyvinylacetate interacts with 0.6 g of VCl₄ as in Example 1 in a solution of carbon tetrachloride. The yield of light-brown product containing 2.15 percent of vanadium (component A) is 1.3 g.

Under conditions of Example 1, the reactor is loaded with 0.14 g of the obtained product and 0.64 g of (C₂ H₅)₂ AlCl. The polymerization process is continued for three hours. The yield of polyethylene is 31.5 g, which corresponds to the yield of 10.5 kg/g V. The polymer is characterized by the content of 0.19 double bonds per 1000 carbon atoms, 60 per cent of them having vinyl and 40 per cent vinylidene (in the absence of trans-vinylene) saturation. The physico-mechanical tests have shown that the polymer is characterized by the yield point of 245 kg/sq.cm, neck length 1.3, tensile strength 350 kg/sq.cm, elongation at break over 200 per cent.

EXAMPLE 4

Under conditions of Example 1, to 17.4 g of polyethylene-powder 1.1 g of vinylacetate is grafted, 5.9 g of the product is hydrolyzed as in Example 1, to prepare 5.1 g of hydrolyzed polyethylene-gr.-polyvinylacetate. Under conditions of Example 1, reacted are 2.4 g of the obtained carrier in a suspension of 200 ml of toluene and 0.1 g of (C₅ H₅)₂ TiCl₂ to prepare 2.3 g of light pink powder containing 0.54 mg of Ti/g of the product, component A of the catalyst for polymerization. The polymerization is continued in benzene in conditions as specified in Example 1. The reactor is loaded with 0.45 g of (C₅ H₅)₂ TiCl₂ bonded chemically with the surface of hydrolyzed polyethylene-gr.-polyvinylacetate and 0.28 g of (iso-C₄ H₉)₂ AlCl. The polymerization is carried out for four hours to prepare 7.5 g of high-molecular polyethylene (30 kg/g Ti).

EXAMPLE 5

Under conditions of Example 1 reacted in benzene are 2.4 g of hydrolyzed polyethylene-gr.-polyvinylacetate, obtained in Example 4, and 0.94 g of Ti(OC₄ H₉)₄, to prepare powder whose colour is the same as that of the starting polymer. The powder contains 0.74 mg of Ti/g of the product. The polymerization is carried out in benzene as in Example 1. The reactor is loaded with 0.49 g of the obtained product and 0.3 g of Al(C₂ H₅)₂ Cl. The polymerization is continued for four hours to give 16 g of polyethylene (44 kg/g Ti). The index of melt fluidity is 0.3412 g/10 minutes.

EXAMPLE 6

Vinylacetate (0.34 g) is grafted to polystyrene (1.7 g) having the molecular weight of 35,000 as in Example 1, except that the irradiation intensity is 1.0 Mrad per hour, the absorbed dose of gamma radiation is 4.5 Mrad. The yield is 1.9 g, the degree of grafting is 20 percent. The hydrolysis is carried out as in Example 1, to obtain 1.6 g of polymer carrier. The carrier then reacts with excess TiCl₄ to prepare 1.4 g of component A of the catalyst of polymerization, copolymerization and oligomerization of olefins and diolefins, containing 68 mg Ti/g of the product. The reactor is loaded with 0.0428 g of this product and 0.96 g of (C₂ H₅)₂ AlCl to prepare 29 g of polyethylene (10 kg/g of Ti).

EXAMPLE 7

Vinylacetate (1.3 g) is grafted to a copolymer of ethylene with propylene (7.8 g) containing 1.4 mole percent of propolylene links, as described in Example 1. After hydrolysis, 3.4 g of the obtained poly(ethylene-co-propylene)-gr.-polyvinylacetate, 3.1 g of hydrolyzed copolymer are obtained which react with 0.94 g of VOCl₃, as described in Example 1, to prepare 3.0 g of brown powder containing 54.1 mg V/g. In polymerization with 0.071 g of this product and 0.950 g of (C₂ H₅)₂ AlCl, 43 g of polyethylene are prepared (14 kg/g V).

EXAMPLE 8

A reactor is loaded with 0.6 g of VOCl₃ bonded chemically with hydrolyzed poly(ethylene-co-propylene)-gr.-polyvinylacetate obtained in Example 7, and containing 54.1 mg/of V/g and 0.66 g of (C₂ H₅)₂ AlCl. The composition of the gaseous mixture delivered to the polymerization is as follows: ethylene 65.4 percent by volume, propylene 34.6 percent by volume, the total pressure in the reactor being 5.0 atm. The copolymerization is continued for one hour. The yield of elastic, rubber-like copolymer containing 45 mole percent of propylene and 55 mole percent of ethylene is 24 g. Its total unsaturation is 1.0 double bond per 1000 carbon atoms (50 percent of vinylidene, 30 percent of trans-vinylene, and 20 percent of vinyl bonds). The physico-mechanical tests have shown that the polymer can be referred to the class of rubber-like ethylene-propylene polymers (S -figurative extension curve); tensile strength is 120 kg/sq.cm., elongation over 330 percent.

EXAMPLE 9

Methyvinylketone (3.0 g) is grafted to polyethylene powder (70 g) having the specific surface is 1.6 sq.m per gram, in conditions as described in Example 1. The irradiation intensity is 0.15 Mrad/hr (42 roentgen per sec) and it is maintained constant for ten hours. The absorbed dose of gamma radiation is 1.5 Mrad. After grafting, the product is kept in benzene for 27 hours to remove homopolymer of polymethylvinylketone that may remain in the product, passed through a filter, and dried in a vacuum drier at 80° C. to constant weight. The grafting degree is 4.2 percent; the radiation-chemical yield is 4 × 10² molecules/100 eV. The infra-red spectrum of polyethylene-gr.-polyethylvinylketone, in addition to the main bands of polyethylene, contains also an intense absorption band at 1728 cm⁻¹, which is due to the valence oscillations of the carbonyl group of the grafted fragments.

Carbonyl groups are reduced to hydroxyl groups as follows.

A suspension consisting of 150 ml of pure freshly distilled cyclohexane and 30 g of polyethylene with grafted polymethylvinylketone, are placed in an argon atmosphere into a three-neck flask provided with a reflux condenser and a dividing funnel. At temperature of 60° C. and with intense stirring, 50 ml of ether suspension of LiAlH₄ (12 g of LiAlH₄) are added in drops from a dividing funnel in the course of one hour. The reaction mixture is kept for further 60 minutes at this temperature with stirring and then excess LiAlH₄ is removed and 50 ml of a 10 percent HCl are added. The polymer is rinsed successively with water, alcohol, and petroleum ether at 80° C. and 1 mm Hg for 14 hours. The analysis of the infra-red spectra of the obtained polymer shows that the reduction of the carbonyl groups is almost complete: in addition to a very weak absorption band at 1725 cm⁻¹, a wide and intense band with the maximum at 3445 cm⁻¹ is observed, which is due to the valence oscillations of hydroxyl group. The polymer has the following structure ##STR66##

The OH-group content (determined by the Verley method) is 1.47 percent. They are located only on the surface of polyethylene. The compound of the transition metal is fixed chemically on the surface of such a polymer carrier (preparing component A) by a procedure described in Example 1. The suspension containing 4.1 g of the reduced polyethylene-gr.-polymethyvinylketone in 100 ml of CCl₄ is reacted with 0.9 of VCl₄ in 30 ml of CCl₄, at a temperature of 70° C., for three hours. The product is filtered in an inert atmosphere, washed to remove free components, and dried on a vacuum filter, to prepare 4.0 g of light brown powder containing 17.5 ml of V/g -component A of the catalyst.

The reactor of the polymerization plant is loaded in conditions of Example 1 with 0.1192 g of the obtained product. 150 ml of benzene as solvent, and 0.5288 g of Al(C₂ H₅)₂ Cl.

Under conditions of Example 10, reacted are 0.1372 g of the obtained product and 0.4 g of (iso-C₄ H₉)₂ AlCl, to prepare 16 g of linear polyethylene (10kg/g V).

EXAMPLE 17

Mesityl oxide (4-methyl-3-pentene-2-one) is grafted to polyethylene powder as in Example 9. To 30.0 g of polyethylene grafted are 2.5 g of mesityl oxide (irradiation intensity is 1.0 Mrad/hour; absorbed dose 60 Mrad). After grafting, the product is placed in benzene and kept for 24 hours, then filtered, and dried to constant weight, to obtain 30.5 g of polyethylene-gr.-poly(4-methyl-3-pentene-2-one).
